NatWest has been in the news after an IT problem at the bank caused widespread disruption to accounts. Payments into and out of accounts were not made, leaving customers of the bank and others expecting to be paid from NatWest accounts in limbo. On Tuesday, the bank said the backlog had been cleared for NatWest and Royal Bank of Scotland customers, but problems remained at Ulster Bank.

Susan Allen, director of customer services at RBS, has agreed to answer your questions live between 2pm and 2.30pm today. She will be unable to answer questions about individual cases – these should be addressed to staff at branches or at the bank's call centre (telephone 0161 931 9959 or 08457 77 77 66 or 0800 656 9639) – but will be able to answer more general questions about what went wrong and how the bank intends to put things right.
